the amount of water vapor in the air, expressed as a percentage of the maximum amount that the air could hold at the given temperature; the ratio of the actual water vapor pressure to the saturation vapor pressure. Abbreviation: RH, rh. -
absolute humidity
the humidity of the atmosphere, usually expressed as the number of grams of water contained in 1 cubic metre of air -

heat index
a number representing the effect of temperature and humidity on humans by combining the two variables into an “apparent” temperature, introduced as a replacement for the temperature-humidity index: a temperature of 90° and relative humidity of 65 percent combine to produce a heat index of 102.
